Storm Transposition and Climate Change

Thursday, April 10, 2014

NE CSC Principal Investigator Ken Potter and colleagues are using “storm transposition” to evaluate the vulnerability of communities to the kinds of flood risk that are likely to increase due to climate change.

They model model flooding conditions in particular locations using data from an extreme storm that recently occurred in a nearby location. For example, their work modeling the impact of extreme events on the Lake Mendota watershed, which includes Madison, Wisconsin indicates that a transposed storm would have been more damaging than any storm to date. Throughout the modeling process they have shared methods and results with city and county engineers and, once results are available, will work with city and county personnel to evaluate the effectiveness of existing lake management practices and stormwater management ordinances.
